Yes harassment happens in real life, none of us are denying that. However, we're talking about something that happened in a game at this point in time, which was not harassment. If and when harassment happens at any other time out side of here then it needs to be dealt with then and there, not here. I don't know why you're so stuck on this. About your other statement, I do make defamatory remarks about myself all the time because I'm overweight and know that I need to get into shape and yet I have absolutely no problem with people making fat jokes, because that's all they are: jokes. There are people who do take things a little too far, but they are very few and far in between.
And since you asked for it: Your comments are literally giving me cancer.
Edit: Also, I think the word you're looking for is "derogatory" not "defamatory", just an FYI.
